STUMP FULLER.

Application filed May 11,

.The object of my invention is to provide a stump pulling apparatus by means of which stumps can be easily and quickly pulled and the cable unwound from the winding drum easily and quickly for application to another stump.

A further object is to provide a stump pulling machine which can be easily and quickly adapted for handling the pulled stumps and gathering them together in a pile for burning or other purposes.

. Other objects of the invention will appear from the following-detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure l is a side elevation of a stump pulling machine embodying my invention,-

Figure 2 is a sectional view on the line 2-2 of Figure 1, V

Figure 7 is a detail view of the auxiliary or supplemental drum which is used when the machine is piling stumps, I

FigureS is a detail sectional view, showing the manner of securing the sections of the auxiliary drum together,

Figure is a sectional view on the line 10-10 of Figure 9.

In the drawing, 2 represents a suitable frame having skids 3 at the ends and suitable runners, not shown, may be provided for moving the "frame and the mechanism thereon from place to place. A drum l is provided at one end of said frame and has a stud 5 fitting within a socket 6 in a lower bearing plate 7 secured to said frame and an upper bearing plate 8 has an opening therein for the upper portion 9 of the drum, said bearing plate being supported by suitable means, such as legs 10. Cables 11 and 12 connect the bearing plate 7 and the bearview on the line 1922. Serial No. 560,229.

ing plate 8 with a suitable stake or post 13, thereby securely anchoring the drum. A ring i l is loosely mounted on the upper portion of the drum and seated on the plate 8 and is provided with a sweep 15 to which the horses or other power is attached. Plates 16,

are mounted on the ring 14 and have links 1'? connecting them with said ring. Arbralre band 18 encircles the upper drum section 9 and has one end secured to a stud 19 mounted on the ring 14:. A lever 20 is pivoted at 21 in the plate 16 and is connected to the other end of the strap 18, as shown in Figure 3, so that when the lever is oscillated, the strap may be tightened or loosened on the drum, as desired. The plates 16 have ratchet teeth 22 and a dog 28 ismounted on the lever for engagement with these teeth for locking the lever in its adjusted positions. l'Vhen the band is tightened, the

ring and the sweep will be locked on the drum and when the band is loosened, the ring and sweep may turn freely on the drum without revolving it. I am thus able to wind up the cable on the drum in the operation of pulling the stump and then, by releasing the band, the .drum may berevolved backward by pulling on the cable and the operator allowed to move the cable out to be placed on another stump without the necessity of disconnecting the team or power from the sweep.

, At the opposite end of the frame from the winding drum I provide an upright mast 2 1, preferably E i-shaped, having its legs rigidly secured to the frame and provided with a sheave through which the cable passes from the drum to the stump. A step 26 is mounted in the frame between the legsot the mast and adapted to receive the lower end of a boom 27 which rocks or oscillates freely in said step. The upper end of the mast has a guy rope 28 and a pulley block 29 connected to a loop 30 at the top of the mast has a running connection with a cable 31 which extends to the block 32 that is connected to the upper outer end of. the boom 27. A Windlass 33 is mounted on the mast and has a winding crank 34 and a locking pin 35. By means of this Windlass the cable maybe wound up and the boom raised or lowered, as desired. lVhen the desired elevation of the boom has been obtained, the Windlass will be locked and the boom will then be supported in this position until the operator desires to use it at perhaps another elevation. After a number of stumps have been pulled, the operator will pass the cable over a pulley block 36 that is connected to the outer end of the boom and from thence the cable is carried to and attached to the pulled stumps and then, upon operating the winding drum, the stumps may be lifted and deposited in a pile.

For the purpose of handling the stumps more. rapidly and winding up the cable faster, I prefer to provide an auxiliary drum consisting of scctionsii'i which are arranged to encircle the main drum, as indicated in Figure 4t, and be seated against shoulders 38 on said drum. Holes 39 are provided in the sections of the auxiliary drum and coupling linlzs L0 are provided having ends fitting within the holes 39 and bridging the joint between the sections and holding them in place, as indicated in Figure 5. The cable is carried outwardly through a notch 4-1 in one of the auxiliary drum sec tions and from thence passes to the sheaves for attachment to the stumps for lifting and piling them at any desired point. 7 ()bviously, the winding of the cable on this auxiliary drum will have the eil'ect of reducing the power of the drum but will operate it faster to wind up the cable more rapidly than would be the case it the same drum was used "for both pulling the stumps and piling them.

When the pulling operation has been completed, the operator will place the auxiliary sections in position for winding the cable thereon and then pass the cable over the sheaves for attachment to the stumps.

I claim as my invention:

1. A stump pulling machine comprising a frame, a winding drum mounted thereon and provided with a vertical extension, a cable for said drum, a ring loosely encircling said extension, a sweep mounted on said ring, aband encircling said extension and connected with said ring and manually controlled means tor tightening or releasing said band to lock or release said ring and sweep.

:2. A stump pulling machine comprising a frame, a drum mounted therein, a cable for said drum, a ring loosely encircling said drum, a sweep mounted on said ring and adapted for attaching power thereto, a band encircling said drum adjacent to said ring and having one end connected to said ring, a lever pivoted on said ring and c0nnected with the other end of said band, movement of said lever operating to tighten or loosen said band to lock or release said ring, and means for holding said lever in its adjusted positions.

3. A stump pulling machine comprisin a frame, a drum mounted therein, a cable 1or said drain, a ring loosely encircling said drum,-a sweep mounted in said ring, a band encircling said drum, plates having ratchet teeth connected with said ring and also with one end of said band, and a lever connected with the other end of said band and having a dog for engaging the teeth of said ratchetnates, whereby said band may be tightened on said drum or loosened, as desired.

t. A stump pulling machine comprising a frame, a winding drum mounted thereon and provided with an extension, a cable for said drum, :1 member loosely encircling said extension, a sweep on said member, means encircling said extension for locking said member thereon, and a manually cont-rolled device for operating said encircling means.

5. A stump pulling machine comprising a. frame, a drum mounted therein,'a cable to be wound on said drum as it is revolved, semi-cylindrical drum sections adapted to enclose the main drum and having holes near the longitudinal edges and U-shaped links fitting said holes for securing the abutting edges of said sections together to form an auxiliary drum on which said cable may be wound, and a boom having a sheave over which the cable is passed from said auxiliary drum for attachment to the pulled stumps for lifting and piling them.

In witness whereof, I have hereunto set ny hand this 8 day of May, 1922.

WILLIAM A. WILSON.
